Assessment

Primary outcomes

Every adverse event occurred in the period from the first liposuction to the last observation day will be assessed by the relation with the treatment, incidence rate, severity, and seriousness.

Key secondary outcomes

(1)volume (rate of engraftment): change in the period from enrollment to 6 months after the last lipoinjection
(2) projection (rate of restoration): change in the period from the enrollment to 6 months after the last lipoinjection
(3) evaluation of cells: evaluation of cultivation process and cultivated cells
(4) questionnaire to the subjects
(5) rate of completion of the treatment

Interventions/Control_1

(1) Placement and removal of tissue expander (TE)
For breast reconstruction, TE will be placed in the target breast in the first operation and removed in the fourth operation.

(2) Liposuction
In the first, the second, and the third operations with intervals of 4 to 6 months, fat will be aspirated from abdomen, buttocks, or thighs of patient. The fat will be used for injection into the breast and for preparation of ASC. The ASC prepared from approximately 20 ml of fat will be cultivated and cryopreserved for the next operation.

(3) Lipoinjection
In the second, the third, and the fourth operations, the aspirated fat will be mixed with the cryopreserved ASC and injected into the breast. In each operation, the TE will be taken out from the breast before fat injection and the volume of the TE will be reduced appropriately. After fat injection, the TE will be placed into the breast again.
